I've read people say to use the Oatey red can All Purpose Cement. On the Oatey site they say this:
I don't care about the cure time and no hot water will go through the pipes. I know they're two different kinds of plastics but has anyone used this glue and then the joint leaked?
Can I use All Purpose Cement to join PVC to CPVC?
No. It is not recommended because it takes longer for CPVC to finish the curing process necessary to complete a strong bond after the cement is applied. CPVC is also rated for hot water use which will affect cure times. PVC is not rated for hot water temperatures.
